Tax Lien Investing: How to Buy Liens and Earn Returns

Tax lien investing represents one of the most misunderstood yet potentially lucrative real estate strategies. By purchasing delinquent property tax liens from local governments, investors can earn government-guaranteed interest rates ranging from 8% to 36% annually—or potentially acquire valuable properties for pennies on the dollar.

However, despite the enticing infomercial promises, tax lien investing requires substantial knowledge, due diligence, and capital reserves to execute successfully. This guide provides the comprehensive framework you need to evaluate whether tax lien investing fits your goals.

What Are Tax Liens?

When property owners fail to pay their property taxes, local governments place a tax lien on the property. This lien takes priority over all other debts, including mortgages—making it the most senior secured position possible.

To recover unpaid taxes quickly rather than waiting years, many municipalities sell these tax liens to private investors through public auctions. As the lien purchaser, you're entitled to:

1. Repayment of your investment when the property owner pays the delinquent taxes
2. Statutory interest at rates set by state law (typically 8-36% annually)
3. Foreclosure rights if the property owner doesn't redeem the lien within the redemption period

How Tax Lien Investing Works

The Tax Lien Process

Step 1: Property owner fails to pay property taxes.

Step 2: After a specified delinquency period (varies by jurisdiction), the government offers the tax lien for sale at public auction.

Step 3: Investors bid on the lien. Bidding methods vary:

• Bid down the interest rate: Winner accepts lowest interest rate
• Premium bidding: Winner pays above the lien amount
• Random selection: Winners chosen by lottery at statutory rate
• Rotational bidding: Winners rotate based on attendance or registration

Step 4: Winning investor pays the lien amount plus fees to the government.

Step 5: Property owner has a redemption period (6 months to 4+ years, depending on state) to pay the delinquent taxes plus interest and penalties to the lien holder.

Step 6a: If redeemed, investor receives their principal plus accrued interest.

Step 6b: If not redeemed, investor can initiate foreclosure proceedings to potentially take ownership of the property.

State-by-State Variations

Tax lien laws vary dramatically by state. Some states are tax lien states (sell liens), others are tax deed states (sell properties directly), and some use hybrid systems.

Major Tax Lien States:

• Florida: 18% interest, 2-year redemption, competitive auctions
• Arizona: 16% interest, 3-year redemption, bid-down auctions
• Illinois: 18-36% penalty, 2.5-3 year redemption, competitive market
• Iowa: 24% annual interest, 1.75-year redemption
• Indiana: 10-25% penalty, 1-year redemption
• Mississippi: 18% interest, 2-year redemption
• New Jersey: 18% interest, 2-year redemption, popular with investors
• Maryland: Variable rates, competitive auctions

Tax Deed States (different strategy):

• Georgia, Texas, [California](/blog/california-heloc-guide) (sell property directly, not liens)

Always verify current laws, as states periodically modify tax sale procedures.

Why Invest in Tax Liens?

Government-Guaranteed Interest Rates

Tax lien interest rates are set by statute, not market conditions. These rates often dramatically exceed conventional fixed-income investments:

• Florida: Up to 18% annually
• Illinois: 18-36% penalty after 6 months
• Iowa: 24% annually
• Maryland: Variable, often 12-20%

These returns are backed by the full faith and credit of the taxing authority and secured by real property.

Priority Lien Position

Tax liens are superior to all other claims:

• Mortgages (first and second position)
• HOA liens
• Mechanics liens
• Judgment liens

If foreclosure occurs, your tax lien gets paid before everyone else—providing exceptional security.

Potential Property Acquisition

While most liens are redeemed (typically 95-98%), non-redeemed liens can lead to property ownership through foreclosure:

• Properties acquired for back taxes only
• Potential to purchase $100,000 property for $5,000 in taxes
• No mortgage debt transfers to you

However, this outcome is rarer than advertised, and the properties involved are often problematic.

Diversification Benefits

Tax liens provide diversification:

• Uncorrelated with stock market volatility
• Different risk profile than property ownership
• Various jurisdictions and property types
• Short to medium-term time horizons (1-3 years typically)

Relatively Passive (If Redeemed)

When liens are redeemed (the most common outcome), your involvement is minimal:

• Purchase at auction
• Wait for redemption
• Collect principal plus interest

No [property management](/blog/property-management-complete-guide), tenant issues, or maintenance concerns.

Finding Tax Lien Auctions

Local Government Websites

Most counties publish tax sale information on their treasurer or tax collector websites, including:

• Auction dates and times
• Lists of available liens
• Bidding procedures and rules
• Registration requirements
• Payment methods accepted

Search: "[County Name] tax lien sale" or "[County Name] treasurer tax sale"

Online Tax Lien Platforms

Some jurisdictions conduct auctions online:

• Bid4Assets: Platform for many East Coast counties
• RealAuction: Handles various county auctions
• Grant Street Group: Manages auctions for multiple municipalities
• County-specific platforms: Many large counties have proprietary systems

Tax Lien Directories

• National Tax Lien Association: Industry organization with resources
• Tax Sale Lists: Subscription services compiling sale information
• State treasurer websites: Often list all counties' sale schedules

Networking

Join local real estate investor associations and tax lien investing groups to learn about upcoming sales and share strategies.

Due Diligence: Evaluating Tax Liens

Property Research

Never bid on a tax lien without researching the underlying property:

Physical inspection: Drive by the property to verify:

• Existence (properties can be demolished or never built)
• Condition (is it habitable or a teardown?)
• Occupancy (occupied, vacant, condemned?)
• Neighborhood quality

Property records:

• Ownership history
• Property characteristics (size, bedrooms, bathrooms)
• Recent sales comparables
• Assessed value vs. market value

Environmental concerns:

• Flood zones
• Contamination (former gas stations, industrial sites)
• Wetlands or unbuildable lots

Title Search

Conduct a thorough title search to identify:

Other liens:

• First and second mortgages
• Federal tax liens (IRS liens may trump your position in some cases)
• HOA liens
• Mechanics liens

Ownership issues:

• Estate situations (deceased owners)
• Bankruptcies (may delay redemption or foreclosure)
• Corporate ownership

Property type:

• Verify the property is real estate (not mobile homes or boats)
• Confirm legal access to the property
• Identify easements or restrictions

Valuation Analysis

Calculate property value conservatively:

Market value estimate: Use recent comparable sales, not assessed value (which may be inflated or outdated).

Equity cushion: Ensure substantial equity exists beyond all liens:

Example:

• Property market value: $150,000
• First mortgage: $90,000
• Tax lien amount: $8,000
• Equity cushion: $52,000 (35% of value)

Never buy tax liens on properties with [negative equity](/blog/negative-equity-explained) or thin margins—foreclosure won't recover your investment.

Redemption Probability Assessment

Estimate likelihood of redemption based on:

Occupancy: Owner-occupied properties have 98%+ redemption rates. Vacant or abandoned properties may be non-redemptions.

Equity position: Properties with substantial equity are almost always redeemed (owners or lenders won't lose $100,000 of equity over $5,000 in taxes).

Property condition: Well-maintained homes indicate responsible owners likely to redeem.

Lien size: Small tax debts on valuable properties almost always get redeemed.

Return Calculation

For redemption scenario:

Tax lien amount: $10,000 Interest rate: 18% annually Redemption period: 2 years Total return: $10,000 × 36% = $3,600 ROI: 36% total over 2 years (approximately 16.5% annualized)

For foreclosure scenario:

Tax lien cost: $5,000 Foreclosure costs (legal, filing, etc.): $3,000 Total investment: $8,000 Property value (conservative): $80,000 [Renovation](/blog/bathroom-renovation-cost-guide) needed: $15,000 After-repair value: $90,000 Sale proceeds (after commissions): $84,000 Net profit: $61,000 ($84,000 - $8,000 - $15,000) ROI: 762%

However, foreclosure scenarios rarely work this cleanly—factor in holding costs, delays, and potential complications.

Tax Lien Auction Strategies

Competitive Bidding Environments

In hot markets (Florida, Arizona), hundreds of investors compete:

Bid down interest: Auctions where the winner accepts the lowest interest rate. Rates may get bid down to 1-2% or even 0.25%, eliminating the profit.

Premium bidding: Winner pays above the lien amount. You might pay $8,000 for a $5,000 lien, reducing effective returns.

Strategy: Focus on less desirable liens that experienced investors skip (rural properties, smaller amounts, complicated titles).

Less Competitive Markets

Smaller counties and less-known sale dates offer better opportunities:

• Full statutory interest rates
• No premiums
• Reasonable acquisition prices

Trade-off: Fewer investors often means lower-quality inventory (there's a reason pros aren't bidding).

Portfolio Approach

Rather than chasing the "perfect" lien:

• Purchase 10-20 smaller liens across different properties
• Diversify by location, property type, and lien size
• Accept that some won't perform as expected
• Aggregate returns across the portfolio

Subsequent Tax Years

After purchasing a lien, you can often purchase subsequent years' taxes on the same property:

• Protects your initial investment
• Compounds your returns
• Increases total claim if you foreclose

Example: You buy a 2024 tax lien for $5,000. In 2025, you can purchase the 2025 tax lien for $5,200, bringing your total investment to $10,200. If the owner redeems in 2026, you earn interest on the cumulative amount.

The Foreclosure Process

If the redemption period expires without payment, you can initiate foreclosure to potentially acquire the property.

Tax Deed Application

File for a tax deed with the county:

• Submit application with required fees ($500-$2,000)
• Prove compliance with all notice requirements
• Obtain court order (in judicial states)

Notice Requirements

Strict legal procedures must be followed:

• Certified mail to property owner
• Notice to mortgage holders
• Publication in legal newspapers
• Posting on the property

Failure to comply perfectly can invalidate your foreclosure—hire an experienced attorney.

Redemption Right Extensions

Many states allow extended redemption rights during foreclosure:

• Additional 30-60 days after filing
• Opportunities for installment payment plans
• Court-ordered extensions in hardship cases

Taking Ownership

If no redemption occurs:

• Court issues tax deed transferring ownership to you
• Record the deed
• Evict occupants if necessary
• Secure and insure the property

Wiped-Out Liens

Tax deed foreclosure typically eliminates:

• Mortgages
• Second liens
• Most junior liens

Exceptions:

• Federal tax liens (IRS) may survive in some jurisdictions
• Municipal liens (water, sewer)
• Current-year property taxes

Common Pitfalls and Risks

IRS Liens (Federal Tax Liens)

Federal tax liens enjoy a special 120-day right of redemption even after you foreclose. If the IRS exercises this right:

• You receive your investment back plus 6% interest
• You lose the property
• Your anticipated profit disappears

Always search for federal tax liens before bidding. Properties with IRS liens are higher risk.

Worthless Properties

Many non-redeemed tax liens involve properties with serious issues:

• Environmental contamination (cleanup costs exceed value)
• Landlocked parcels with no legal access
• Condemned structures requiring demolition
• Unbuildable lots in flood zones or wetlands
• Properties in dying towns with no market

Due diligence is essential—if a property seems too good to be true, investigate why the owner abandoned it.

Bankruptcy Complications

If the property owner files bankruptcy:

• Automatic stay halts foreclosure proceedings
• Redemption periods may be extended
• Your lien remains valid but enforcement is delayed
• Bankruptcy attorney fees and delays eat into returns

Homestead Exemptions and Extended Redemption

Some states grant longer redemption periods for:

• Primary residences (homesteaded properties)
• Elderly or disabled owners
• Agricultural land

These extensions can tie up your capital for 3-5+ years.

Overbidding and Low Returns

Competitive auctions can destroy returns:

• Bidding interest rates down to 1-2%
• Paying premiums above lien amounts
• Emotional bidding without proper analysis

Discipline is critical—walk away if bidding exceeds your target returns.

Occupant Eviction Challenges

Taking ownership through foreclosure doesn't guarantee vacant possession:

• Former owners may refuse to leave
• Tenants may have lease rights
• Squatters may occupy abandoned properties
• Eviction can take 3-6 months and cost $3,000-$10,000

Hidden Costs

Tax lien investing involves numerous expenses beyond the purchase price:

• Auction registration fees
• Subsequent years' taxes
• Title searches ($200-$500 each)
• Legal fees for foreclosure ($2,000-$5,000+)
• Property maintenance and securing costs
• Insurance
• Potential environmental remediation

Tax Implications

Interest Income

Interest earned from redeemed tax liens is taxable as ordinary income at your marginal rate. You'll receive Form 1099-INT from the taxing authority.

Capital Gains

If you foreclose and acquire property, then sell:

• Your cost basis is the total tax lien investment plus foreclosure costs
• Gain is calculated as sale price minus cost basis minus selling expenses
• Short-term capital gain (<1 year holding) or long-term (>1 year)

[Self-Directed IRA](/blog/dscr-loan-self-directed-ira) Investing

Tax liens can be held in self-directed IRAs:

• Tax-deferred or tax-free growth (traditional or Roth)
• All income flows back to the IRA
• Unrelated Business Income Tax (UBIT) generally doesn't apply
• Prohibited transaction rules apply if you benefit personally

Alternative: Tax Deed Investing

Some states sell properties directly (tax deeds) rather than liens:

Tax Deed States: Georgia, Texas, California, New Mexico

Tax Deed Process:

• Government forecloses on delinquent properties
• Properties sold at auction to highest bidder
• Winner receives immediate ownership (no redemption period)
• Mortgages and other liens are wiped out

Pros:

• Immediate ownership
• No waiting for redemption
• Clear title (in most cases)
• Potential for below-market acquisition

Cons:

• Higher capital requirement (buying whole properties)
• More competition from flippers and landlords
• Property condition often poor
• Eviction and cleanup responsibilities

Getting Started: Action Plan

Step 1: Education (1-2 months)

• Research your state's tax lien laws thoroughly
• Study 3-5 target counties' specific procedures
• Read books: "Profit by Investing in Real Estate Tax Liens" by Larry Loftis
• Join tax lien investing forums and local investor groups
• Watch actual auctions (online or in person) before bidding

Step 2: Build Your Team (1 month)

• [Real estate attorney](/blog/how-to-build-real-estate-team) with foreclosure experience
• Title company or abstractor
• CPA familiar with tax lien income reporting
• Contractors (if planning to acquire properties)

Step 3: Compile Due Diligence Resources

• Access to property records (county assessor websites)
• Title search capabilities
• Comparable sales databases (Zillow, Realtor.com, MLS access)
• Mapping tools (Google Maps, county GIS systems)

Step 4: Start Small (First 6-12 months)

• Attend 2-3 auctions as an observer before bidding
• Start with 1-3 small liens in one county
• Choose properties you can physically inspect
• Target owner-occupied homes with high redemption probability
• Avoid complex titles and problem properties initially

Step 5: Scale Gradually

• Expand to multiple counties as you gain experience
• Diversify across property types and locations
• Consider junior tax liens and riskier properties only after mastering basics
• Develop systems for tracking redemption dates and subsequent taxes

Frequently Asked Questions

Are tax lien returns really guaranteed?

The interest rate is set by state statute, and your lien has priority over other debts, but "guaranteed" is misleading. You're guaranteed the right to collect that interest if/when the property owner redeems. If they don't redeem, you must foreclose, which involves costs, delays, and risks.

What percentage of tax liens are redeemed?

Typically 95-98% of tax liens are redeemed. Properties with substantial equity, owner occupancy, and active mortgages almost always get redeemed. Non-redemptions usually involve abandoned, worthless, or severely distressed properties.

Can I really buy a house for $500 in back taxes?

Technically possible but extremely rare. Properties with minimal tax debts that go unredeemed usually have serious problems: environmental contamination, no legal access, condemned structure, or other title defects that make them essentially worthless.

How much money do I need to start?

Minimum $5,000-$10,000 for your first liens, but $25,000-$50,000 provides better diversification across multiple liens. You'll also need reserves for subsequent years' taxes ($5,000+) and potential foreclosure costs ($3,000-$10,000).

Do I need to attend auctions in person?

Many counties now offer online auctions, allowing remote participation. However, physical inspections of properties before bidding are still essential—never bid sight unseen.

What happens if I win a bid but can't pay?

You'll typically forfeit a deposit and may be banned from future auctions in that county. Some jurisdictions impose penalties or fines. Always have funds ready before bidding.

Can I use leverage (borrowed money) for tax liens?

Generally, conventional lenders don't finance tax lien purchases. Some investors use:

• Home equity lines of credit
• Business lines of credit
• Private money lenders (expensive)
• Partners who fund deals for equity shares

What if the property is in bankruptcy?

The bankruptcy automatic stay halts collection and foreclosure. Your lien remains valid, but enforcement is delayed pending bankruptcy resolution. Chapter 13 may impose payment plans; Chapter 7 may discharge the owner's personal liability but not the property lien.

Are there scams in tax lien investing?

Yes. Beware of:

• Seminars promising "no-risk guaranteed returns"
• Turnkey services charging huge markups
• Lists of "pre-screened" liens at inflated prices
• Properties in undesirable or inaccessible locations

Always conduct independent due diligence.

How do I handle evictions after foreclosure?

Hire an eviction attorney and follow state-specific landlord-tenant laws. Cash-for-keys (paying occupants to leave voluntarily) often costs less and resolves faster than formal eviction proceedings.

---

Tax lien investing can deliver exceptional returns and provide access to below-market properties—but only for disciplined investors who conduct thorough due diligence, understand local laws, and maintain realistic expectations. The high redemption rates mean you'll primarily earn interest income, not acquire properties. If you're comfortable with that reality and commit to mastering the nuances of your target markets, tax liens can become a valuable portfolio diversification strategy.
